ROTARY ENGINE.

Specification of Letters Patent.

Patented Apr. 22, 1919.

Application filed July 12, 1917. Serial No. 180,151.

To all whom it may concern:

Be it known that 1, JOHN HAGEL, a citizen of the United States, and resident of Goldfield, in the county of Esmeralda and State of Nevada, have invented certain new and useful Improvements in Rotary Engines, of i which the following is a specification.

The present invention relates to improve- I ments in engines; the dominant object of the engine which tend toward the attainment of invention being to provide a rotary engine receiving its driving power from either combustible gas or steam, which, due to the absence of intricate valve operating mechanism, abutments, etc., will produce its maximum speed and power with but a minimum amount of fuel.

Another object of the invention is to provide the engine with an improved form of piston, the same being light, compact and capable of rotating without the loss of any of the force or power of the motive fluid.

Other objects-of the invention are to provide novel intake valve operating mechanism, whereby the admittance of motive fluid to rotor chamber will be properly timed; to provide yieldable packing for the piston or rotor to prevent loss of the motive power, and further, to provide means for effecting operation of the sliding abutment in' the rotor chamber at predetermined intervals.

Other independent objects are to provide features of construction of portions of the the above aims irrespective of the relation in which they are used.

The inventlon accordingly consists of the, features of constructlon, combinatlon of elements and the arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings,wherein is shown one of various possible embodiments of my invention Figure 1 is a vertical section through the improved engine;

Fig. 2 is a horizontal section therethrough;

Fig. 3 is a fragmentary transverse section in detail through the rotor chamber showing the yieldable piston packing;

Fig. 4 is a fragmentary detail in elevation of the intake valve operating means;

Fig. 5 is a similar view of the sliding abutment operating means; and

Fig. 6 is a fragmentary detail in section showing the mounting of the sliding abutment in the rotor chamber.

Similar characters of reference refer to similar parts throughout the several views of the drawings.

Having more particular reference to the drawings, 1 designates the base of my improved engine, which is formed upon the lowermost portions of the several substantially L-shaped circular sections 2 and 3 which form the rotor chamber of the engine; these sections having marginal flanges 9. and 3 formed upon their adjacent ends whereby bolts 4 or other suitable fastening devices may be passed therethrough for an obvious purpose. It is to be noted in this connection, that the arrangeemnt of the sec tions 2 and- 3 which constitute the rotor chamber is such as to provide a circular slot or way upon the inner s rface thereof.

Arranged concentrically of the rotor chamber of the engine is a power shaft 5, the opposite portions of which are rotatably supported in bearing pillars 6. A segment 7 having a bearing collar 8 formed thereon is keyed to the power shaft 5, as at 9, andhas its outermost portion arranged adjacent the inner surface of the rotor chamber and is movable over the slot or way formed therein.

Rotatable within the rotor chamber and arranged in the said slot or way formed therein is a circular band 10 substantially T-shaped in cross section and having aper tured brackets 11 secured to its opposite ends, which brackets are connected by means of a bolt 12 carrying compression springs 13 on its opposite portions and in engagement with said brackets. A bridging piece 1 1 is arranged over the jointure between the op posite ends of the circular band 10 and, obviously, serves to prevent the loss of motive power from the rotor chamber during operation of the engine. In this connection, it is to be understood that the circular band 10 may be readily flexed and as a consequence by adjusting the tension of the springs 13 through the medium of the connecting bolt 12. I

A piston or rotor 15 is mounted in the rotor chamber and is provided with grooves or seats in which packing'strips having interlocking ends as designated by the numeral 16 are arranged, compression springs l'T'being arranged in suitable bores formed in the piston and having bearing upon the said packing strips in order that close engagement between the same and the sides of the rotor chamber will be insured. Set screws 18 or like fastening devices are passed through complementally arranged openings formed in the outermost portion of the seg ment 7 and the circular-band 10 into engagement with screw threaded bores formed in the rotor 15 and serve as means for connecting said elements and causing rotation of the same collectively.

Thickened portions 19 are arranged upon the sections 2 and 3 constituting the rotor chamber and are provided with a way through which the sliding abutment 20movable transversely of the rotor chamber passes. A hood 21 is arranged over the thickened portions 19 while strips 22 T- shaped in cross section are arranged upon the opposite sides thereof and serve as means for closing the way through which the slide ing abutment 20 travels; these strips 22 being secured in position through the medium of set screws 23. A stuffing gland 24: is formed in the outer portion of the hood 21 and receives therethrough a stem 25 engaged with the slidable abutment 20, the stem in turn having an eye formed on its outer end in order that the same may be received between the bifurcated portion of a lever 26 and pivotally connected thereto. as at 27. As shown in Fig. 2, the remaining end of the lever 26. is pivotally engaged with a bracket arm 28 secured to the outer side ofthe rotor chamber and having an. opening formed intermediate its end, the purpose of which will be subsequently apparent. An operating rod 29 is slidably secured to one side of the rotor chamber in a bracket 30 and passes through the opening in the bracket arm 28 into pivotal connection with the lever 26 throughthe medium of a link 31. The inner end of the rod 29 is bifurcated and has journalcd therebetween a roller 32, which roller is intermittently engaged by the cam '33 keyed onto the power shaft 5. of the engine. In the opposite side of-the rotor chamber thereis formed an intake port, over which a valve casing 3-l,having a eomplemental port therein is arranged and secured by set screws 35. An intake valve,preferably of the puppet type is arranged in the casing 34 and has the stem 36 thereof provided with a bifurcated portion 37 carrying a roller 38 therein. A cam 39 is keyed onto the adjacent portion of the power shaft 5 and as Wlll be understood, intermittently engages the roller 38, thus, unseating the intake valve and allowing the admittance of motive fluid to the rotor chamber.

It may. be here noted that should the improved rotary engine receive its power from combustible gas, a spark plug or Other suit able form of ignition means may be arranged and entended into the rotor chan1- ber. Further, it is to be also noted that the cam 33 Which actuates-the rod; 29 is of such rma ion to a ow the h ld ng of th sliding abutment in its retracted or inoperav P tion f r br ef Period of ime in er ha th ro or l =mayf 7ee y P s t ame i F e ithin th peripher l s rfac o the ret r hamber and at the cmp et en o the power stroke of the rotor 15 is an exhaust ort so. t is per-t be ngat all tim pen n Orderh t he eto eham rmay be thoroughly scavenged of the, spent or exhausted notive fluid previous to the inke of a fresheh se- Manifes lyi the c nstruc ion sh wn is capable of considerable modification and such modification as is within the scope of my c aims. 1 con ider within t spirit of my nven iee- I claim I?
